A semitrailer crashed into the median, scattering chunks of cement across both the westbound and eastbound lanes. The crash also ruptured the semitrailer's fuel and oil tanks, spilling about 100 gallons of diesel fuel and 45 gallons of oil on the highway, said Michigan State Police Trooper Derrick White.

"It was just a huge mess," White said of the crash and the ongoing cleanup.

The semitrailer crashed about 9:30 a.m. Traffic had slowed in the westbound lanes of I-94 because of an unrelated crash about a half mile ahead near Airport Road, White said. A small utility trailer became unhooked from the back of a truck and overturned on the highway.

The driver of the semitrailer did not see the slowing traffic in time and turned into the median to avoid a collision, White said. The driver hit his breaks, lost control and crashed into the concrete barrier. The crash broke off several large chunks of concrete, some of which ended up in the eastbound lanes. Three vehicles heading east were damaged by concrete, White said.

Both lanes of westbound I-94 and one lane of eastbound I-94 were closed for about an hour. The left lane of westbound I-94 will likely remain closed for a few hours, White said Monday afternoon.

A front-end loader was needed to remove some of the concrete from the highway. The trucking company called a crew from Young's Environmental Cleanup out of Marshall to clean up the oil and diesel fuel, said Blackman-Leoni Township Public Safety Deputy Director Jon Johnston.

The Michigan State Police handled the crash. Blackman-Leoni public safety officers responded to assist, handle the fuel spill and to be on scene in case a fire started. The Jackson County Road Commission was also on scene. The Michigan Department of Environmental Quality and the Michigan Department of Transportation were also notified.

No one was injured. The driver of the semitrailer was cited for a basic violation of the speed law, White said.

The left lane of westbound I-94 will likely remained closed until about 3 or 4 p.m., White said.
